Nous proposons le cryptage perceptuel basé sur le cube (C-PE), qui consiste en un brouillage de cube, une rotation de cube, une transformation négative/positive de cube et un mélange de composants de couleur de cube, et décrivons son application au système de cryptage puis compression (ETC). de mouvement JPEG (MJPEG). En particulier, la rotation du cube remplace les blocs dans les images d'origine par ceux des autres images, mais également par les côtés du cube en profondeur (côtés spatio-temporels), contrairement au cryptage perceptuel basé sur les blocs (B-PE) conventionnel. Puisqu'il rend l'observation intra-bloc plus difficile et empêche le déchiffrement non autorisé à partir d'une seule trame, il est plus robuste que B-PE contre les méthodes d'attaque sans aucune clé de déchiffrement. Cependant, comme les trames chiffrées incluant les blocs des côtés spatio-temporels affectent légèrement les performances de compression MJPEG, nous concevons également une version de C-PE sans côtés spatio-temporels (NSS-C-PE) qui n'affecte guère les performances de compression. C-PE rend la séquence vidéo cryptée robuste contre la seule attaque algorithmique par force brute (ABF) basée sur une seule image avec seulement 21 cubes. Les résultats expérimentaux montrent l’efficacité de la compression et la robustesse du chiffrement du système ETC basé sur C-PE/NSS-C-PE. Le système ETC basé sur C-PE montre des résultats mitigés en fonction des vidéos, tandis que le système ETC basé sur NSS-C-PE montre que le BD-PSNR peut être supprimé jusqu'à environ -0.03 dB, indépendamment des vidéos.

Abstract: We propose the cube-based perceptual encryption (C-PE), which consists of cube scrambling, cube rotation, cube negative/positive transformation, and cube color component shuffling, and describe its application to the encryption-then-compression (ETC) system of Motion JPEG (MJPEG). Especially, cube rotation replaces the blocks in the original frames with ones in not only the other frames but also the depth-wise cube sides (spatiotemporal sides) unlike conventional block-based perceptual encryption (B-PE). Since it makes intra-block observation more difficult and prevents unauthorized decryption from only a single frame, it is more robust than B-PE against attack methods without any decryption key. However, because the encrypted frames including the blocks from the spatiotemporal sides affect the MJPEG compression performance slightly, we also devise a version of C-PE with no spatiotemporal sides (NSS-C-PE) that hardly affects compression performance. C-PE makes the encrypted video sequence robust against the only single frame-based algorithmic brute force (ABF) attack with only 21 cubes. The experimental results show the compression efficiency and encryption robustness of the C-PE/NSS-C-PE-based ETC system. C-PE-based ETC system shows mixed results depending on videos, whereas NSS-C-PE-based ETC system shows that the BD-PSNR can be suppressed to about -0.03dB not depending on videos.
